Principal contractor HSE support

Taking on the principal contractor role changes what you are carrying. The duties are yours whether or not the subcontractors who created the risk did their part properly.

Who this is for

  • Builders who have become the principal contractor on a project larger than usual.
  • Project teams standardising what they accept from subcontractors.
  • Companies who need documented assurance across several trades at once.

The problem it solves

The exposure is rarely the principal contractor's own paperwork. It is the twenty subcontractor SWMS accepted without being read, the plant that arrived without records, and the high-risk work that started before anyone verified a control. None of that shows up until it matters.

What Obras does

  • Set the standard for what a subcontractor SWMS must contain before it is accepted.
  • Verify subcontractor documentation against the work they are actually doing.
  • Build the site control systems — permits, plant verification, high-risk work checks — so acceptance is a process rather than a signature.
  • Document the assurance, so the position is evidenced rather than assumed.

What you receive

  • An acceptance standard your team can apply consistently.
  • Verified subcontractor documentation, with what was rejected and why.
  • Site control systems in your name.
  • A documented assurance position for the project.

What happens next

Tell us the project, the trades and where you are in it. Principal contractor work is always scoped to the job — there is no standard price because there is no standard project.

Where we work. Standard service area: Gold Coast, Logan, Brisbane, Moreton Bay and Sunshine Coast. Outside this area, contact Obras for availability and a tailored quote — additional travel and site attendance costs may apply.

Travel and site attendance. Travel and site attendance charges may apply depending on location. Obras will confirm any additional travel cost before work proceeds — quoted in advance based on location and attendance requirements, never added afterwards.

What Obras does not do. We do not give legal advice, and we do not certify or guarantee compliance — nobody honestly can. Your officers keep every duty under the WHS Act. Engagements are subject to an agreed written scope and terms. All professional-service prices exclude GST unless expressly stated otherwise.
